VANCOUVER, Oct. 31 /CNW/ - Tumi Resources Limited ("Tumi" and/or the
"Company") (TSXv-TM; OTCBB - TUMIF; Frankfurt - TUY). David Henstridge,
President, is pleased to announce the start of an airborne (by helicopter)
electromagnetic (EM) geophysical survey (the "Survey") over the Company's
wholly-owned Tomtebo, Oster Silvberg and Vitturn licence areas located in the
Bergslagen District, Sweden. The Survey will involve approximately 500 line
kms of flying and data recording on lines spaced 100m apart and covering the
licence areas.
Tomtebo: The historic Tomtebo mine is located 25 km southeast of the city
of Falun, Sweden. Earliest records indicate that the Tomtebo mine was first
discovered and developed in the mid-seventeenth century, but detailed
production records were kept only in the early part of the twentieth century.
The mine has been closed since 1969. The host rocks are cordierite quartzite
and mica schists which grade into biotite-andalusite bearing quartzite. These
rocks are derived from highly potassic rhyolite tuffs.
Copper ore at the Tomtebo mine occurred in small folds as lenses or
stringers in an anticline. Between 1836 and 1837, 1,841 tons of copper and
1,077 tons of sulphur were produced. The copper content of the ore varied from
3.0% to 5.3% between the years 1915 and 1919. The average ore grade during the
last phase of mining, between 1965 and 1969, was about 1% copper, 1% zinc and
35% sulphur. An assay of fairly pure chalcopyrite (copper ore) gave 140 g/t
silver and 9 g/t gold.
Oster Silverberg: The Oster Silverberg mine, located 27 km south of the
city of Falun, was once the chief producer of silver in Sweden in the
fourteenth and fifteenth centuries, but there has been no production since the
mid- 1920's. The host rock is generally a metamorphosed, fine-grained, bedded
potassic rhyolite tuff. Near the ore contacts, the rock is often classified as
an "ore quartzite" which is actually the tuff that has been altered to mostly
quartz, garnet, mica, minor andalusite and other metamorphic minerals. The
mineral bodies at Oster Silvberg are found in cross-fractures, spatially
related to the metamorphosed tuff formations, which appear to have been formed
by the regional folding that deformed the host rocks.
The principal ore was an argentiferous galena that formed a columnar body
to the 220 metre level of the mine. Flanking the galena to the north and
southeast occur some narrower pyrite-sphalerite orebodies containing very
little galena and traces of chalcopyrite, quartz and fluorite. Complete mine
production and grade records are not available. Early records indicate that
silver production exceeded 32,000 ozs per year. One tabulation shows a total
of only 2,900 ozs of silver mined in thirteen different years between 1636 and
1920. The mine suffered several shut-downs in these centuries due to rock
caves, owing in part to the reduced production during these times. Various
assays from the 17th and 18th centuries show that the ¿ster Silvberg galena
carried from 1,053 to 4,335 g/t silver. In addition, the silver recovered
contained about 10% gold (from 100 to 430 g/t.)
Vitturn: The Vitturn licence covers a series of base metal, silver and
iron occurrences developed along the western belt of mineralization in the
Bergslagen district. The project targets a flexure position in the western
mineralized belt where occurrences are limestone-hosted and provide potential
for large replacement style deposits. Mineralization is associated with
strongly magnetic features which trend for 10 km through the Vitturn claim.
Mr Henstridge stated "these three licences cover old mines and surface
mineralization that have had little modern exploration undertaken within them.
The EM survey will cover many kms of prospective host rocks along strike and
around the old mines and over surface mineralizaton. There is a strong
possibility that there are other mineralized horizons at depth, along strike
or in parallel structures that do not come to surface. We are very hopeful
that the survey will define EM targets that will be drilled as soon as
practicable".
The qualified person for Tumi's projects, David Henstridge, a Fellow of
the Australian Institute of Mining and Metallurgy and a Member of the
Australian Institute of Geoscientists, has visited the Tomtebo, Oster Silvberg
and Vitturn licences in the Bergslagen District, Sweden, and has verified the
